Set to true to restrict the output of findOneStepGVD to return only the indeterminates for which their geometric vertex decomposition is degenerate. Default value false. Following the notation of oneStepGVD, a geometric vertex decomposition is degenerate if either $\sqrt{C_{y, I}} = \sqrt{N_{y, I}}$ or if $C_{y, I} = \langle 1 \rangle$, and is nondegenerate otherwise.
The object OnlyDegenerate is a symbol.
